LIQUID-CRYSTALLINE MEDIUM

摘要

Disclosed are a liquid-crystalline medium which contains at least one compound of formula IA,;;and in addition at least one compound of formula CC-n-V and/or CC-V-V1,;;where the percentage proportion of the compound(s) of formula IA is greater than or equal to the percentage proportion of CC-n-V, and/or the percentage proportion of the compound(s) of formula IA is greater than the percentage proportion of CC-V-V1, where the percentage proportion is based on the liquid-crystalline medium,

and the use thereof in active-matrix displays, in particular based on the VA, PSA, PVA, PS-VA, SS-VA, SA-VA, PA-VA, PALC, FFS, PS-FFS, PS-IPS or IPS effect.

1. A liquid-crystalline medium, comprising a compound of formula IA, in which Z1 denotes a single bond, —CH2CH2—, —CH═CH—, —CH2O—, —OCH2—, —CF2O—, —OCF2—, —COO—, —OCO—, —C2F4—, —C≡C—, —CF═CF—, —CH═CHCHO— or —CH2CF2O—, and at least one compound of formula CC-n-V and/or CC-V-V1, where n denotes 2, 3, 4, 5 or 6, with the provisos that
the percentage proportion of the compounds of formula IA is greater than or equal to the percentage proportion of the compounds of formula CC-n-V, and/or
the percentage proportion of the compounds of formula IA is greater than the percentage proportion of the compounds of formula CC-V-V1, where the percentage proportion is in each case based on the liquid-crystalline medium.
